Description
Technical field
The utility model belongs to the clamping field of workpiece or cutter, is specifically related to a kind of rolling clamp system.
Background technology
In machine tooling, after usually needing to use clamping device that Workpiece clamping is fixing, then carry out follow-up processing, so clamping device is widely used in work pieces process field.
Clamping device all comprises power source and clamp system usually, in existing oblique-wedge clamping system, usual employing roller and tapered wedges coordinate, power source drives tapered wedges, and tapered wedges drives clamp system clamping work pieces, and this clamping mode has the effect of increase clamping force, in addition, roller and tapered wedges coordinate, and both frictions reduce, so can reduce wearing and tearing.But for yielding workpiece, roller and tapered wedges coordinate clamping easily to cause workpiece deformation.
Utility model content
For the defect that above-mentioned prior art exists, the purpose of this utility model is to provide one to be both convenient to clamp yielding workpiece, can reduce again the rolling clamp system of self wearing and tearing.
For achieving the above object, the technical solution of the utility model is: rolling clamp system, comprise frame, transmission mechanism and clamp system, wherein, described transmission mechanism comprises screw rod, sliding sleeve, clamp nut, transmission arm and roller, described screw rod is vertically arranged and bottom is connected with frame, described sliding sleeve to be sheathed on screw rod and to be compressed by clamp nut, the back-moving spring be sheathed on screw rod is provided with between described sliding sleeve bottom and screw rod, described sliding sleeve bottom and transmission arm one end hinged, the transmission arm other end is provided with roller; Described clamp system comprises cursor, pressing plate and is positioned at baffle plate in frame and relative with pressing plate, hinged with frame in the middle part of described cursor, and pressing plate described in upper articulation, side, bottom and roller offset.
When adopting technique scheme, by regulating clamp nut in the vertical position of screw rod, thus control to slide over vertical position.Workpiece to be placed in frame and to offset with baffle plate, when sliding sleeve moves down, due to transmission arm one end and sliding sleeve lower hinge, transmission arm launches, the other end is provided with roller, the side of roller and cursor bottom offsets, in addition, hinged with frame in the middle part of cursor, pressing plate described in upper articulation, so roller urges cursor rotates, now pressing plate moves near baffle plate, thus by Workpiece clamping.The utility model is in the process of clamping work pieces, the sliding sleeve power acted on transmission arm is vertical power, and only some component is along transmission arm length direction, thus the power that transmission arm puts on cursor is less, and the power of the pressing plate workpiece pressing hinged with cursor one end is less.In addition, by roller contact between transmission arm and cursor, wearing and tearing are between the two little, so this programme had both been convenient to clamp yielding workpiece, can reduce again self wearing and tearing.
Further, described screw rod is provided with spacer pin, and sliding sleeve is provided with the spacing hole coordinating spacer pin to slide vertically, thus slides over when screw rod slides, and spacer pin can limit the rotation of sliding sleeve, avoids the interference of transmission arm by rotating torque.
Further, the side of described cursor and roller contact is provided with upper limit bar and lower limit bar, and lower limit bar can prevent roller and cursor from departing from, and upper limit bar can prevent clamping force in clamping process excessive and make workpiece deformation.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail:
Fig. 1 is the structural representation of the utility model rolling clamp system embodiment.
Detailed description of the invention
As shown in Figure 1, a kind of rolling clamp system, comprise frame 1, transmission mechanism and clamp system, wherein, transmission mechanism comprises screw rod 3, sliding sleeve 5, clamp nut 4, transmission arm 6 and roller 11, screw rod 3 vertically arranges and bottom is connected with frame 1, sliding sleeve 5 to be sheathed on screw rod 3 and to be compressed by clamp nut 4, the back-moving spring 2 be sheathed on screw rod 3 is provided with between sliding sleeve 5 bottom and screw rod 3, back-moving spring 2 upper end and sliding sleeve 5 phase top, lower end is supported in frame 1 by spring base, sliding sleeve 5 bottom and transmission arm 6 one end hinged, transmission arm 6 other end is connected with roller 11; Clamp system comprises cursor 10, pressing plate 9 and is positioned at baffle plate 7 in frame 1 and relative with pressing plate 9, hinged with frame 1 in the middle part of cursor 10, upper articulation pressing plate 9, and side, bottom and roller 11 offset.
In the present embodiment, screw rod 3 is provided with spacer pin 13, and sliding sleeve 5 is provided with the spacing hole 12 coordinating spacer pin 13 to slide vertically, thus when sliding sleeve 5 slides on screw rod 3, spacer pin 13 can limit the rotation of sliding sleeve 5, avoids the interference of transmission arm 6 by rotating torque.
The side that cursor 10 contacts with roller 11 is provided with upper limit bar 15 and lower limit bar 14, and lower limit bar 14 can prevent roller 11 and cursor 10 from departing from, and upper limit bar 15 can prevent clamping force in clamping process excessive and workpiece 8 is out of shape.
Concrete use flow process:
As shown in Figure 1, workpiece 8 to be placed in frame 1 and to offset with baffle plate 7, clamp nut 4 is regulated to move down, clamp nut 4 is extruding sliding sleeve 5 downwards, sliding sleeve 5 is moved down, due to transmission arm 6 one end and sliding sleeve 5 lower hinge, transmission arm 6 launches, and the other end is provided with roller 11, and roller 11 offsets with the side of cursor 10 bottom, in addition, hinged with frame 1 in the middle part of cursor 10, upper articulation pressing plate 9, rotates counterclockwise so roller 11 promotes cursor 10, now pressing plate 9 moves near baffle plate 7, thus is clamped by workpiece 8.When needing to unclamp workpiece 8, regulate on clamp nut 4 and move, the back-moving spring 2 be now sheathed on screw rod 3 applies power upwards on sliding sleeve 5, sliding sleeve 5 vertically screw rod 3 moves, now sliding sleeve 5 drives on transmission arm 6 one end and moves, the other end of transmission arm 6 draws in, and the power that roller 11 puts on cursor 10 is withdrawn, and workpiece 8 unclamps by the pressing plate 9 being articulated with cursor 10 upper end.
Above-described is only preferred embodiment of the present utility model; should be understood that; for a person skilled in the art; under the prerequisite not departing from the utility model structure; some distortion and improvement can also be made; these also should be considered as protection domain of the present utility model, and these all can not affect effect and the practical applicability of the utility model enforcement.
